Shocking Service from FNB Home Loans Department!

My husband and I did a joint application for a bond to purchase a new home. We completed the application and had to wait approximately 3 weeks to hear the outcome of this application. During this time we were not notified why this was taking so long. We continuously had to make lenghthly phone call for our account, to have any action taken. After numerous phone calls and e-mails we eventually got to the stage of FNB sending an evaluator. He had difficulty gaining access and again we were not notified and we had to phone FNB for feedback. We were told the application is withdrawn, no feedback was sent to me advising me of same. Our initial offer to purchase now lapsed and we signed a new offer to purchase sent it back to FNB, again absolutely no response. More lenghlty phones calls and being dealt with by several staff members none of who could help. We sent a new offer to purchase and made a call to confirm that they received same....another week passes and no response. Again numerous phone call later and I am assured an evaluator will be sent soonest...our new offer to purchase is now again about to lapse. Despite the urgency of the matter we only get an offer on the day before our offer laspses with a much higher interest rate than our current bond. We question this and request to speak to a Manager it is now 2 days later and still no response!!!! FNB takes no action unless we phone them and prompt them to do their work! Shocking Service to say the very least!
